Apple Tree Named &#39;Alpigala&#39;

ABSTRACT

‘Alpigala’ is a whole tree mutation of ‘Gala’, the fruit of which is notable for its early coloring, very dark overcolor, and strongly defined stripes.

Latin name: Malus domestica.

Variety denomination: ‘Alpigala’.

BACKGROUND OF THE VARIETY

‘Alpigala’ is a new and distinct variety of apple tree (Malus domestica). ‘Alpigala’ is a natural whole tree mutation of ‘Gala’ (U.S. Plant Pat. No. 3,637) discovered by the inventor in an established ‘Gala’ orchard at Manosque, France in 2010. Propagative material of the newly discovered tree was asexually reproduced by budding at Doué la Fontaine, France in 2010 and subsequently fruited through successive generations at Doué la Fontaine, France. ‘Alpigala’ has been observed to remain true to type over successive asexually propagated generations.

BRIEF DESCRIPTION OF THE VARIETY

‘Alpigala’ was first selected for its early coloring, very dark overcolor, and strongly defined stripes as compared to parent ‘Gala’ and other ‘Gala’ sports. Comparisons of ‘Alpigala’ to similar ‘Gala’-type varieties ‘Galaval’ (U.S. Plant Pat. No. 19,909) and ‘Biagent’ (U.S. Plant Pat. No. 10,016) are shown in the following table:

DETAILED BOTANICAL DESCRIPTION OF THE VARIETY

The following-detailed botanical description is based on observations made during 2015 and 2016 at Seiches sur le Loir, France of 3 and 4 year old trees grown on Pajam® 2 Cepiland rootstock (not patented). All colors are described according to The Royal Horticultural Society Mini Colour Chart. It should be understood that the characteristics described will vary somewhat depending upon cultural practices and climatic conditions, and will vary with location and season. Quantified measurements are expressed as an average of measurements taken from a number of individual plants of the new variety. The measurements of any individual plant or any group of plants of the new variety may vary from the stated average.
